Browning 1042472 Qd Bushed V Belt Sheave 1 Groove

Product Description

The BROWNING 1042472 is a single-groove, QD (Quick Detachable) bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts an H-style QD bushing and accommodates bore diameters from 0.375 inches to 1.5 inches, making it adaptable to a wide range of shaft sizes without requiring a dedicated machined bore. The outside diameter measures 5.25 inches, with a Belt Pitch A diameter of 4.5 inches and a Belt Pitch B diameter of 4.9 inches. At 2.75 pounds, it is a compact, field-ready component typically installed by HVAC technicians and mechanical contractors during blower drive assembly or motor replacement work.

This sheave is suited for residential and light commercial HVAC air handlers, rooftop units, and belt-driven blower assemblies where A-section or B-section V belts are used. The QD bushing system allows fast installation and removal without special pullers, making it a practical choice for service technicians performing scheduled maintenance or drive component replacement on belt-driven fan and blower systems. The H bushing style is a standard QD size compatible with sheaves in this diameter class.

Compatibility

Designed as an OEM-style replacement or upgrade sheave for belt-driven blower and fan assemblies that use H-style QD bushings and single-groove A or B section V belts. Specific system compatibility depends on shaft diameter and drive ratio requirements of the application.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the unit before servicing any drive components. The H-style QD bushing must be sourced and installed separately; torque the bushing cap screws evenly per the bushing manufacturer's specification printed on the bushing itself. Verify belt tension and sheave alignment after installation before returning the system to service.
